Defensive publication

ABSTRACT

COMPOSITIONS ARE DESCRIBED WHICH ARE USEFUL FOR PROVIDING A STRIPPABLE PROTECTIVE COATING ON VARIOUS SUBSTRATES (E.G. AUTOMOBILE MOLDINGS). THE COMPOSITIONS COMPRISE PETROLEUM WAX, ETHYLENE-ISOBUTYL ACRYLATE COPOLYMER, ETHYLENE-VINYL ACETATE COPOLYMER AND A ROSIN ESTER. SUITABLE ETHYLENE-ISBOUTYL ACRYLATE COPOLYMERS CONTAIN ABOUT 20 TO ABOUT 32 WEIGHT PERCENT ISOBUTYL ACRYLATE AND HAVE A MELT INDEX OF ABOUT 0.5 TO ABOUT 260. SUITABLE ETHYLENE-VINYL ACETATE COPOLYMERS CONTAIN ABOUT 18 TO ABOUT 29 PERCENT BY WEIGHT VINYL ACETATE AND HAVE A MELT INDEX OF FROM ABOUT 0.5 TO ABOUT 250. SUITABLE ROSIN ESTERS ARE THE GLYCEROL AND PENTAERYTHRITOL ESTER OF ROSINS SUCH AS PALE WOOD ROSIN, HYDROGENATED ROSIN AND POLYMERIZED ROSIN. THE SUBSTRATE CAN BE MADE OF ALUMINUM, ANODIZED ALUMINUM, PAINTED ALUMINUM, STAINLESS STEEL, VINYL, ACRYLONITRILE-BUTADIENE-STYRENE (ABS) POLYMER OR VARIOUS COMBINATIONS OF THESE MATERIALS. THE VARIOUS MATERIALS CAN BE PRESENT IN THE FOLLOWING AMOUNTS (PARTS BY WEIGHT): PETROLEUM WAX-30 TO 60; ETHYLENE-ISOBUTYL ACRYLATE COPOLYMER-15 TO 40; ETHYLENE-VINYL ACETATE COPOLYMER-10 TO 40; ROSIN ESTERS-5 TO 20.

lint. Cl. 1365b 33/00, 33/04 US. Cl. 117-6 No Drawing. 16 Pages Specification Compositions are described which are useful for providing a stn'ppable protective coating on various substrates (e.g. automobile moldings). The compositions comprise petroleum Wax, ethylene-isobutyl acrylate copolymer, ethylene-vinyl acetate copolymer and a rosin ester. Suitable ethylene-isboutyl acrylate copolymers contain about 20 to about 32 weight percent isobutyl acrylate and have a melt index of about 0.5 to about 260. Suitable ethylene-vinyl acetate copolymers contain about 18 to about 29 percent by Weight vinyl acetate and have a melt index of from about 0.5 to about 250. Suitable rosin esters are the glycerol and pentaerythritol ester of rosins such as pale Wood rosin, hydrogenated rosin and pol'yrnerized rosin. The substrate can be made of aluminum, anodized aluminum, painted aluminum, stainless steel, vinyl, acrylonitrile-butadiene-styrene (ABS) polymer or various combinations of these materials. The various materials can be present in the following amounts (parts by weight): petroleum Wax-30 to 60; ethyiene-isobutyl acrylate copo1ymer15 to 40; ethylene-vinyl acetate copo1ymer--10 to 40; rosin esters-5 to 20.
